TSMC completed the purchase of a second 900-acre parcel in Arizona, doubling its land holdings as the world’s largest contract chipmaker accelerates U.S. expansion. The additional space addresses capacity constraints at its original 1,100-acre site.

The original Arizona site was designed for six wafer fabrication plants, two advanced packaging facilities, and a research center. Some facilities will now shift to the newly acquired land, with remaining space reserved for future flexibility.
TSMC’s first Arizona fab started volume production in Q4 2024 using 4-nanometer technology. The facility now delivers yields and performance matching the company’s premier Taiwan operations.
TSMC Arizona began producing Nvidia’s Blackwell GPUs with its N4P process in October 2025. The success has accelerated timelines for additional facilities.
Construction of the second fab is complete with tool installation planned for 2026. The plant will employ 3-nanometer technology with volume production starting in the second half of 2027.
A third fab broke ground in April 2025 and will manufacture 2-nanometer chips. Volume production targets the decade’s end. The company is applying for permits for a fourth fab and its first advanced packaging plant.
Thursday’s U.S.-Taiwan trade deal reduces tariffs on Taiwanese goods to 15% from 20%. The agreement encompasses $250 billion in direct investments from Taiwanese firms plus $250 billion in credit guarantees.
U.S. Commerce Secretary Howard Lutnick said the goal is relocating 40% of Taiwan’s semiconductor supply chain to American soil. The $250 billion includes TSMC’s $100 billion commitment announced in 2025.
TSMC has committed $165 billion to U.S. operations to date. Profit margins remain higher in Taiwan due to lower labor costs, and the company will continue developing cutting-edge technologies there where research teams work alongside manufacturing.
TSMC shares climbed more than 3% in Taipei trading Friday following the earnings report and trade deal announcement.
